Description

  The present invention relates to an operating device for operating a plug lid provided at a drain outlet.

  2. Description of the Related Art Conventionally, a push button type is known as an operation device for remotely operating a plug lid and opening and closing a drain outlet. As such an operation device, there are an operation button, an operation mechanism having a support shaft that supports the operation button in a reciprocating manner, a predetermined tank body (for example, a bathtub, a washbasin, etc.) and the vicinity thereof And a guide member that guides the movement of the operation button on the outer periphery of the operation button and a cylindrical attachment member that is attached to the outer periphery of the guide member are proposed. (For example, see Patent Document 1).

  Moreover, a guide member is attached with respect to the said attachment target object by pinching | interposing the said attachment target object between the collar part which protrudes in the outer peripheral side provided in the one end side of itself, and an attachment member. More specifically, a male screw portion is formed on the outer periphery of the guide member, and a female screw portion capable of screwing the male screw portion is formed on the inner periphery of the mounting member. And after arrange | positioning an attachment member to the back side of an attachment target object so that it may become substantially coaxial with the through-hole provided in the attachment target object, while inserting a guide member in the said through-hole, the said guide member is rotated. Thereby, the external thread part of a guide member is screwed by the internal thread part of an attachment member, and an attachment target object is inserted | pinched between a collar part and an attachment member. As a result, the guide member is attached to the attachment object.

  By the way, since a collar part is comprised thickly generally, it is inferior to external appearance quality, and water tends to accumulate on the outer periphery of a collar part, and is easy to get dirt. Therefore, in recent years, a technique has been proposed in which a portion corresponding to the collar portion is configured by a metal plate flange made of a metal plate, thereby reducing the thickness of the collar portion and improving appearance quality and cleanability (for example, patents). Reference 2 etc.). In the technique, the metal plate flange is fixed to a guide cylinder having an external thread portion on the outer periphery. More specifically, the metal plate flange is fixed to the guide cylinder by engaging the claw provided in the guide cylinder with the hook provided in the metal plate flange.

JP 2011-174346 A JP 2012-172512 A

  However, with the technique described in Patent Document 2, it is not easy to firmly fix the metal plate flange to the guide cylinder. For this reason, when an excessive force is applied to the metal plate flange in the direction away from the guide cylinder, such as when the male screw portion of the guide member is excessively screwed into the female screw portion of the mounting member, the guide There is a possibility that the metal plate flange falls off from the cylindrical body and the guide member is damaged.

  Furthermore, in order to obtain the guide member, it is necessary to provide a fixing structure (hanging hole or claw portion) on the guide cylinder or the metal plate flange, and in the manufacturing process, a process for fixing both ( For example, it is necessary to provide an assembly process and an insert molding process. For this reason, there is a risk of increasing manufacturing costs and reducing productivity.

  In addition, in the prior art, when the male threaded portion of the guide member is screwed into the female threaded portion of the mounting member, the collar portion (metal plate flange) rubs on the surface of the mounting target object. There is a risk of wrinkles on the surface. Since this flange is covered with the flange (metal plate flange), it usually does not appear to the outside. For example, a guide member having a relatively small outer diameter with replacement of the guide member, etc. In the case of newly using, etc., wrinkles may be exposed to the outside, leading to a decrease in appearance quality.

  The present invention has been made in view of the above circumstances, and its purpose is to more reliably prevent breakage of the guide member and formation of wrinkles on the surface of the object to be attached, and reduction in manufacturing cost, and An object of the present invention is to provide an operating device capable of improving productivity.

  In the following, each means suitable for solving the above-described object will be described in terms of items. In addition, the effect specific to the means to respond | corresponds as needed is added.

Means 1. A cylinder that protrudes to the outer peripheral side and has a flange portion at one end portion that is disposed on the surface of the tank body or an attachment object that is a structure in the vicinity thereof, and a part of itself is inserted through the through hole of the attachment object A guide member,
An operation button disposed on the inner periphery of the guide member;
An operation mechanism having a support shaft for supporting the operation button in a movable state along the central axis of the guide member;
A transmission member connected to the operation mechanism and transmitting the displacement of the operation button to the plug lid side provided in the drainage port of the tank body;
An operating device comprising: a cylindrical mounting member having an internal thread portion on an inner periphery thereof capable of screwing an external thread portion provided on an outer periphery of the guide member;
The guide member is
It has the collar at one end of itself, and has an annular projection protruding radially inward at the other end of itself, and is made of a highly rigid material, and the operation buttons are arranged on the inner periphery. A cylindrical flange portion,
It has a hook-like locking part protruding outward in the radial direction and locked to the annular protrusion on the inner periphery of the flange part, and the male screw part arranged outside the flange part, and has its own central axis A cylindrical tightening portion that can be rotated relative to the flange portion with the rotation axis as a rotation axis, and at least a part of the operation mechanism can be inserted into the inner periphery thereof,
The operating device, wherein the guide member is attached to the attachment object by screwing the male screw part into the female screw part and sandwiching the attachment object by the flange part and the attachment member.

  Examples of the “high rigidity material” include metals such as stainless steel and brass, resin materials such as PPS, and ceramic materials.

  According to the above means 1, since the flange portion is formed of a highly rigid material, the flange portion can be made thin. Therefore, it is possible to improve appearance quality and cleanability.

  Further, according to the above-described means 1, the guide member is configured to be attached to the attachment object by screwing the male screw portion of the tightening portion with the female screw portion of the attachment member. This is a state in which the hook-shaped locking portion is locked to an annular annular protrusion provided on the flange portion. Therefore, the locking force of the tightening portion with respect to the flange portion can be made extremely large. As a result, it is difficult to cause a situation in which the tightening portion is detached from the flange portion as the guide member (tightening portion) is screwed to the mounting member, and the guide member can be more reliably prevented from being damaged.

  Further, according to the above means 1, the tightening portion is merely locked to the flange portion, so that a structure for fixing both and a process for fixing both are not required. Therefore, it is possible to reduce manufacturing costs and improve productivity.

  In addition, according to the above means 1, the tightening portion is rotatable relative to the flange portion, and the guide member is attached by rotating the tightening portion and screwing the male screw portion into the female screw portion. It is configured to be attached to. Therefore, when the male screw portion is screwed into the female screw portion, the flange portion does not rub and move on the surface of the attachment target, and it is possible to prevent the surface of the attachment target from becoming wrinkled. As a result, it is possible to further improve the appearance quality.

  Mean 2. The operation device according to claim 1, wherein a holding portion that holds the operation mechanism is provided on an inner periphery of the attachment member.

  As in the above-described conventional technique (the technique described in Japanese Patent Application Laid-Open No. 2012-172512), it is conceivable to provide a holding part for holding the operation mechanism in the guide member (flange part or fastening part). Here, it is difficult to provide the holding portion on the inner periphery of the flange portion from the viewpoint of space, for example, it is necessary to provide a space for moving the operation buttons. Therefore, it is conceivable to provide a holding portion in the tightening portion. However, in the case where the holding portion is provided in the tightening portion, if the tightening portion is screwed to the mounting member while the operation mechanism is held by the holding portion Then, the transmission member is twisted, and there is a possibility that the transmission of the displacement of the operation button may be hindered. Therefore, when the holding portion is provided in the tightening portion, the operating mechanism and the transmission member are once pulled out to the outside of the attachment object through the through hole, and then the tightening portion is screwed to the mounting member. The operation mechanism needs to be held by the holding unit. However, when such a method is adopted, a great burden is imposed on the installation worker, and the installation workability may be deteriorated. In addition, when the operation mechanism and the transmission member are pulled out, the transmission member may be broken or bent, and the member such as the transmission member may be damaged.

  In this regard, according to the means 2, the holding member that holds the operation mechanism is provided on the attachment member. Therefore, even if the tightening portion is screwed to the mounting member while the operation mechanism is held by the holding portion, the transmission member is not twisted. Furthermore, when the tightening portion is screwed to the mounting member, the operation of temporarily pulling out the operation mechanism and the transmission member is not required, and the tightening portion is screwed to the mounting member while the operation mechanism is held by the holding portion. Can do. As a result, it is possible to more reliably prevent breakage of the transmission member and the like while realizing good mounting workability.

Means 3. The tightening portion is
A cylindrical inner component having the locking portion;
It has the male screw part on the outer periphery, and comprises a cylindrical outer constituent part attached to the inner constituent part,
The operating device according to claim 2, wherein the male screw portion is located on an outer peripheral side with respect to the inner constituent portion.

  In the case where the tightening portion is constituted by one member, the outer diameter of the male screw portion is used to dispose the male screw portion outside the flange portion while locking the locking portion to the annular protrusion on the inner periphery of the flange portion. Needs to be large enough to pass through the inner periphery of the annular protrusion (specifically, the outer diameter of the male screw portion is made smaller than the inner diameter of the annular protrusion). In this case, it is necessary to reduce the inner diameter of the female screw portion provided in the mounting member corresponding to the outer diameter of the male screw portion, and the internal space of the mounting member is also relatively small. Therefore, when the holding portion is provided on the inner periphery of the attachment member as in the above-described means 2, there is a possibility that a sufficient space for providing the holding portion cannot be secured. In particular, when the operation button has a small diameter, the flange part, the tightening part (male thread part), and thus the female thread part have a smaller diameter, and the internal space of the mounting member becomes very small. Therefore, it becomes even more difficult to provide the holding portion on the inner periphery of the mounting member.

  In this regard, according to the means 3, the tightening portion is constituted by the inner constituent portion and the outer constituent portion attached to the inner constituent portion. Therefore, after locking the locking part of the inner component part to the annular protrusion, the male screw part can be arranged outside the flange part by attaching the outer component part to the inner component part. In order to arrange it outside the flange portion, it is not necessary to pass the outer component portion through the inner periphery of the annular protrusion. Therefore, regardless of the inner diameter of the annular protrusion, the outer diameter of the external thread portion provided in the outer constituent portion can be set.

  And according to the said means 3, the external thread part is comprised so that it may be located in an outer peripheral side rather than an inner side structure part, and the outer diameter of an external thread part shall be comparatively large. Therefore, the inner diameter of the female screw portion and thus the internal space of the mounting member can be made sufficiently large. As a result, the holding portion can be provided on the inner periphery of the attachment member, that is, the configuration of the means 2 can be realized very easily.

  Means 4. 4. The operating device according to claim 3, wherein at least a part of the holding part is disposed on an inner periphery of the inner constituent part.

  According to the means 4, the distance from the operation button to the holding portion along the axial direction of the support shaft can be reduced. Therefore, when operating the operation buttons, the operation buttons are less likely to wobble, and the operation buttons can be moved smoothly. As a result, good operability can be obtained.

Means 5. An annular seal member is provided between one end of the attachment member and the attachment object,
5. The device according to claim 1, wherein an internal space in which the operation mechanism is disposed, which is formed on an inner peripheral side from the through hole of the attachment object to the attachment member, is kept watertight. Operating device.

  When water enters between the guide member (flange portion) and the object to be attached and enters the outer peripheral side of the guide member, the intruded water may leak out of the attachment member. In order to prevent water leakage, for example, an annular packing may be provided between the flange of the guide member (flange portion) and the surface of the object to be attached. The packing can be visually recognized from the surface side, or the eaves part protrudes from the surface of the mounting object due to the thickness of the packing. Therefore, there is a possibility that appearance quality may be deteriorated.

  In this regard, according to the above means 5, an annular seal member is provided between one end of the attachment member and the attachment object, and is formed on the inner peripheral side from the through hole of the attachment object to the attachment member. The internal space where the operating mechanism is arranged is kept watertight. Therefore, the water that has entered through between the through hole and the guide member (flange portion) enters the internal space that is kept watertight, and does not leak to the outside of the mounting member. As a result, leakage of water to the outside can be prevented without deteriorating the appearance quality, which is a concern when packing is provided on the surface side of the attachment object.

  Means 6. An over-tightening preventing portion that prevents excessive screwing of the male screw portion with respect to the female screw portion by contacting with the guide member when the male screw portion is screwed with the female screw portion. The operating device according to any one of 1 to 5.

  According to the means 6, when the male screw portion is screwed with the female screw portion, the guide member is brought into contact with the overtightening preventing portion, thereby preventing the male screw portion from being excessively screwed with the female screw portion. . Therefore, it can prevent more reliably that the annular protrusion of a flange part will be damaged with excessive screwing.

That is, the inner component 24 is inserted into the flange portion 21, and the guide member 2 having the outer component 25 attached to the outer periphery of the inner component 24 is inserted into the through hole 103. Then, the attachment member 3 to which the operation mechanism 5 is attached in advance is brought close to the guide member 2 from the lower side, and the attachment member 3 is disposed on the outer periphery of the guide member 2. In this state, by rotating the inner component portion 24, the tightening portion 23 is rotated, and the male screw portion 25A is screwed into the female screw portion 31. Thereby, the guide member 2 will be attached with respect to the bathtub 100. FIG. That is, in the second embodiment, the operation mechanism 5 is not attached after the guide member 2 is attached to the bathtub 100, but the guide member for the bathtub 100 is attached after the operation mechanism 5 is attached to the attachment member 3 in advance. 2 is attached.

The attaching part 23 can be screwed together. As a result, it is possible to more reliably prevent the transmission member 6 and the like from being damaged while realizing good mounting workability.

  Furthermore, the male screw portion 25A is configured to be positioned on the outer peripheral side of the inner component portion 24, and the outer diameter of the male screw portion 25A is relatively large. Therefore, the inner diameter of the female screw portion 31 and the internal space of the mounting member 3 can be made sufficiently large. As a result, it is very easy to provide the holding portion 32 on the inner periphery of the attachment member 3.

  Further, at least a part of the holding portion 32 is disposed on the inner circumference of the inner component portion 24, and the distance from the operation button 4 to the holding portion 32 along the axial direction of the support shaft 51 is small. . Therefore, when the operation button 4 is operated, the operation button 4 is less likely to wobble, and the operation button 4 can be moved smoothly. As a result, good operability can be obtained.

  (A) In the first embodiment, a space is formed between the annular protrusion 21B of the flange portion 21 and the mounting member 3, and when the male screw portion 22A is screwed to the female screw portion 31, the annular protrusion 21B It is comprised so that the attachment member 3 may space apart. On the other hand, as shown in FIG. 4, the attachment member 3 is provided with an overtightening prevention portion 33 that contacts the annular protrusion 21B (guide member 2) when the male screw portion 22A is screwed to the female screw portion 31. It is good. By providing the over-tightening prevention portion 33, it is possible to prevent excessive screwing of the male screw portion 22A with the female screw portion 31. As a result, it is possible to more reliably prevent the annular protrusion 21B from being damaged.

  The over-tightening preventing portion is provided, for example, on the inner periphery of the mounting member 3, and the other end portion (lower end portion) of the tightening portion 22 (guide member 2) when the male screw portion 22 </ b> A is screwed with the female screw portion 31. It may be in contact with. Further, the over-tightening preventing portion need not be integral with the attachment member 3 and may be a separate body. Therefore, for example, as shown in FIG. 5, a ring-shaped overtightening prevention portion 34 is disposed between the annular protrusion 21 </ b> B and the mounting member 3, and when the male screw portion 22 </ b> A is screwed to the female screw portion 31, You may comprise so that the overtightening prevention part 34 may contact the annular protrusion 21B and the attachment member 3. FIG. In this case, by changing the thickness of the overtightening preventing portion 34, it is possible to cope with the bathtubs 100 having different thicknesses. Moreover, it is not necessary to change the structure of the attachment member 3 according to the thickness of the bathtub 100, and the attachment member 3 can be used in common for the various bathtubs 100.

  (B) In the above embodiment, the outer periphery of the flange portion 21A that appears on the surface of the bathtub 100 in the guide member 2 (flange portion 21) has a circular shape in plan view, and the outer periphery of the operation button 4 has a circular shape in plan view. However, the outer peripheral shape of the collar part 21A and the operation button 4 is not particularly limited. For example, the outer peripheral shape of the collar part or the operation button is not flat when viewed in plan view such as a polygonal shape in plan view or an elliptical shape in plan view. It may be circular. As in the prior art, in the method in which the male screw part is provided on the guide member in which the operation button is arranged on the inner periphery, and the male screw part is screwed to the female screw part of the mounting member, the outer periphery of the collar part is non-circular in plan view In this case, depending on the screwing amount of the male threaded portion with respect to the female threaded portion, the direction of the guide member (rivet portion) when the guide member is disposed at the final mounting position varies, and the collar portion is disposed in the target direction. There is a risk that it will not be possible. In addition, when an operation button having a non-circular shape in plan view is used, the direction of the operation button also changes due to the change in the direction of the guide member, and there is a possibility that the operation button cannot be arranged in the target direction. Considering this point, conventionally, the outer peripheral shape of the collar and the operation button is often circular in plan view. On the other hand, according to the said embodiment, direction of the flange part 21 in which the operation button 4 is arrange | positioned in an inner periphery can be changed freely. For this reason, even when a flange portion having a non-circular shape in plan view is used, the collar portion can be reliably arranged in a target direction. Further, even when an operation button having a non-circular shape in plan view is used, the operation button can be surely arranged in a target direction. That is, the configuration of the above embodiment is more effective when the outer peripheral shape of at least one of the collar and the operation button is a non-circular shape in plan view.

  (C) In the said embodiment, although the flange part 21 is formed with iron-type raw materials, such as stainless steel, the constituent material of the flange part 21 should just be a highly rigid material, and is limited to stainless steel etc. is not. Therefore, for example, the flange portion 21 may be formed of a metal such as brass, a resin material such as PPS, or a ceramic material. Moreover, when forming the flange part 21 with a metal material, it is not always necessary to form the flange part 21 by deep drawing, and for example, the flange part 21 may be formed by cutting or the like.

  (D) The structure of the attachment member 3 in the said embodiment is an illustration, Comprising: The structure of the attachment member 3 is not limited to this. Accordingly, for example, a guide member 2 is configured to be attached to the bathtub 100 by using a ring-shaped (short cylindrical) mounting member and screwing the male screw portion of the guide member 2 into the female screw portion of the mounting member. May be. Moreover, when using such an attachment member, the attachment member and the pipe body 107 do not need to be connected.

  (E) In the said embodiment, although the operating device 1 is attached to the bathtub 100 as an attachment target object, the attachment target of the operating device 1 is not restricted to the bathtub 100, For example, tank bodies other than a bathtub It is good also as attaching the operating device 1 (for example, a washbasin, a sink, etc.). Moreover, it is good also as attaching the operating device 1 to the structure (for example, counter of a sink etc.) provided in the vicinity of the tank body.
